Air Explorer is a collection of user-friendly visualization tools for air quality analysts. The tools generate maps, graphs, and data tables dynamically. Currently, the tools access ambient concentration data from EPA’s Air Quality System (AQS). The criteria pollutant data were updated on June 15, 2005. The PM2.5 speciation data were updated on June 30, 2005. The benzene data were updated on February 25, 2005. This is a developmental site. Based on user feedback, we are continually improving the existing tools and developing new ones to meet your needs.

UPDATE (7/14/05) You can now plot and query PM2.5 speciation data at ALL speciation sites, not just those in MSAs.
